Definitions

  • the present invention relates to an intraocular lens (IOL) comprising a lens part with a centre, which lens part is provided on the periphery with two supporting parts (haptics).
  • IOL intraocular lens
  • haptics two supporting parts
  • Lenses of this type are generally known in the state of the art. These are used for replacement of the eye lens after cataract operations, for example.
  • an attempt is made to provide both a distance part and a near part (reading part) in these lenses.
  • this is obtained with the aid of mechanisms which act on the haptics and by which, when a lens system is used, the two or more lenses of such a system are moved in the axial direction. That is to say, the radial movement of the haptics is converted via a mechanism into an axial movement of the lenses.
  • the focal length of the lens system can be changed by bringing two lenses linked one behind the other further apart or closer together and it is possible to provide a distance part and a near part.
  • a lens system of this type is described in U.
  • US-A1-2002/0019667 describes an IOL provided with various optical areas.
  • the document describes an IOL which can be placed in the anterior chamber of the eye and a type which can be placed in the posterior chamber of the eye. All these types are permanently placed.
  • US-A1-2003/0018384 describes an IOL which can be implanted in the posterior chamber of the eye and is deformable along the optical axis, as a result of which the focal length of the IOL changes.
  • U.S. Pat. No. 4,955,902 describes an IOL for placing in an anterior chamber of an eye.
  • the IOL has haptics of different length in order to hold the IOL in a fixed position in the eye eccentrically with respect to the pupil.
  • EP-A1-1.344.503 describes an IOL for the anterior chamber of the eye.
  • the IOL is provided with haptics as engagement part for an insertion tool.
  • the haptics additionally serve for gripping iris tissue.
  • the aim of the present invention is to provide an IOL with which switching from one optical field to another optical field, such as a near part and a distance part, is possible in a simple way.
  • This aim is achieved with an IOL described above in that one supporting part is made radially non-deformable and in that another supporting part is made radially elastically deformable, such that when a radial compression force is applied to the IOL the centre of the lens part moves, the lens part being provided with two optical fields with different optical properties located near the centre.
  • the radial movement of the ciliary muscle is used for the radial movement of the centre of the lens with respect to the optical axis of the eye.
  • shifting from, for example, the distance part to the near part will be obtained for the user almost automatically by the contraction of the ciliary muscle.
  • a possible design of a lens with a distance part and a near part is described in PCT/NL96/00428 in the name of Procornea Holding B.V.
  • the lens described there is a contact lens to be worn on the eye, but it has surprisingly been found that a lens of this type can also be used in an IOL.
  • a lens of this type differs from other lenses in that the reading part is located within the (imaginary) boundary of the distance part. That is to say the reading part is on or within the radius of the outer boundary of the distance part (Rv). If a partial part is used this is preferably made as a segment which extends from the centre of the lens and has an aperture angle of between 90 and 180 degrees and more particularly of between 120 and 170 degrees.
  • the ratio between reading and distance part may mutually vary if two lenses are used. That is to say, one eye has a larger reading part than the other eye.
  • a lens part of this type reacts particularly quickly to the relatively small radial movement of the ciliary muscle.
  • This movement is between 0.1 and 1.5 mm.
  • the force generated by the ciliary muscle can be directly applied for moving the centre of the lens, that is to say no complicated lever mechanisms are needed to convert this movement into an axial movement. Consequently the force which has to be generated by the ciliary muscle for the elastic deformation of the supporting part involved can be relatively small.
  • This force is in the range between 10 and 1000 mN.
  • an IOL of this type will be placed in the posterior chamber of the eye. With this arrangement the IOL will engage the ciliary muscle.
  • the IOL has a diameter of approximately 11-13 mm, specifically approximately 11.5-12 mm.
  • the lens part usually has a diameter of approximately 6-8 mm, specifically 6-7 mm, although the trend at the moment is in the direction of this upper limit or even slightly larger.
  • the non-deformable supporting part is radially non-deformable at a maximum force to be exerted by a ciliary muscle.
  • a ciliary muscle In practice this means that the radially non-deformable part does not deform at a compression force of less than about 100 mN. The non-deformable part often will not deform at a force of up to 1000 mN.
  • the radially elastically deformable supporting part will have to deform radially when the ciliary muscle in an eye exerts a radially directed force thereon.
  • the supporting part will in this case deform to a maximum extent at a maximum force to be exerted by said muscle. Furthermore, said supporting part will preferably hardly deform when the muscle does not exert any force thereon.
  • the supporting part has, though, preferably been designed in such a way that when a force by the muscle is removed the supporting part causes the lens part to return to its initial position. In practice this means that the radially elastically deformable supporting part elastically deforms in the radial direction at a compression force of less than 1000 mN, in practice even at a compression force of less than about 200 mN.
  • the supporting part will start to deform at a force of a minimum of 10 mN. Specifically the supporting part will deform at a force of between about 10 to 200 mN, in particular at a force of between about 10-100 mN.
  • the material used for the lens part and the haptics can be either hydrophilic or hydrophobic.
  • the various elements are preferably made so that they can be folded or rolled up.
  • the haptic can be made of a different material from the lens part in order to optimise the functional properties of the different parts.
  • Both the near part and the distance part can be made both with single strength and as multifocal.
  • the reading part is preferably at the bottom of the lens because this corresponds to the natural inclination of people to look down when reading.
  • the lens parts placed one behind the other in the axial direction.
  • One lens part is made as described above.
  • the other lens part is likewise a lens part provided with one non-deformable haptic and one deformable haptic. However, they are fitted in precisely the reverse positions. This means that when the first lens part moves upwards when the ciliary muscle contracts the second lens part will move downwards with respect to the optical axis of the eye.
  • An additional enhancing effect can be obtained by the combined action of the two lens parts.
  • the second additional lens part is preferably made as a prism or other image compensator, wherein the part with the smallest dimension of the prism is located near the deformable haptic.
  • All the lens parts described above can be provided with a marking, whereby it is possible to assess and if necessary correct the position of the lens part with respect to the eye. This is important for implantation and possible correction.
  • the invention further relates to an intraocular lens (IOL) for implantation in a posterior chamber of the eye, wherein the IOL has a diameter of approximately 11-13 mm and comprises a lens part with a centre, which lens part is provided on the periphery with two supporting parts (haptics), the supporting parts being made mutually differently radially deformable under the influence of a radial compression force, with a mutual difference such that when a radial compression force is applied to the IOL the centre of the lens part moves, the lens part being provided with two optical fields with different optical properties located near the centre.
  • IOL intraocular lens
  • the invention further relates to an intraocular lens (IOL) for implantation in a posterior chamber of the eye, wherein the IOL has a diameter of approximately 11-13 mm and comprises a first lens part with a centre, which first lens part is provided on the periphery with two supporting parts (haptics), wherein the IOL comprises a second lens part axially behind the first lens part, interconnected by means of the supporting parts, which supporting parts are made mutually differently radially deformable under the influence of a radial compression force, with a mutual difference such that when a radial compression force is applied to the IOL, the centre of the first and second lens parts move mutually radially.
  • IOL intraocular lens
  • the invention furthermore relates to an intraocular lens (IOL) for implantation in a posterior chamber of the eye, wherein the IOL has a diameter of approximately 11-13 mm and comprises a first lens part with a centre, which first lens part is provided on the periphery with two supporting parts (haptics), wherein the IOL comprises a second lens part axially behind the first lens part, wherein the second lens part is connected to the first lens part via supporting parts that are connected to the supporting parts, wherein one supporting part is non-deformable in the radial direction and a additional supporting part is radially deformable such that when a radial compression force is applied to the IOL, the centre of the first and second lens parts move mutually radially.
  • IOL intraocular lens
  • the invention further relates to the use of an intraocular lens as described in this document for implantation in a posterior chamber of the eye to replace an eye lens.
  • the intraocular lens described above can be made in any way known in the state of the art.
  • the subsequent processing is turning.
  • the bit can be moved every revolution to and fro in the direction parallel to the rotational axis. This makes it possible to produce the lens part by turning. It is also possible according to an advantageous embodiment to perform the turning so finely that a subsequent polishing operation can be omitted.
  • the material of the lens can be any desired material.
  • FIGS. 1 a, b show in front view and side view a first embodiment of the present invention in the case of a non-contracted ciliary muscle;
  • FIGS. 2 a, b show the embodiment according to FIG. 1 with a contracted ciliary muscle
  • FIG. 3 shows a further embodiment of the present invention wherein the IOL is made up of a lens system.
  • FIG. 1 and more particularly FIG. 1 a an intraocular lens is indicated in its entirety by 1 .
  • This consists of a lens part 2 where so-called haptics or supporting parts 4 and 5 are provided on opposite sides.
  • haptics or supporting parts 4 and 5 are provided on opposite sides.
  • two supporting parts located opposite one another are illustrated. It should be understood that, instead of two, there may be three or more supporting parts.
  • the supporting part 5 has been made elastically deformable, while the supporting part 4 is rigid.
  • the lens part 2 has an optical centre 6 and a horizontal longitudinal centre line 10 .
  • a distance part 9 and a reading part 8 are delimited in the lens part.
  • the reading part 8 extends between 120 and 160 degrees.
  • the distance of the supporting parts 4 and 5 from the outer periphery is made such that when the haptic is not contracted the optical axis 7 of the eye coincides with the optical centre 6 of the lens. This is illustrated in FIG. 1 b. Consequently the user can use the lens for both near vision and distance vision with little effort.
  • the rigid supporting part 4 is in this case substantially solid, while the deformable supporting part 5 is hollow.
  • the supporting part 5 has in this case, for example, a bearing surface that is in contact with, or engages, the ciliary muscle. Said bearing surface is connected by means of elastic connecting parts to the lens part 2 .
  • the bearing surface can be deformable and the connecting parts rigid, or both can be elastically deformable. It is also conceivable to use one connecting part.
  • FIG. 2 shows the state during contracting of the ciliary muscle 14 . Because the non-deformable supporting part 4 is not deformable, all movement will need to come from the elastically deformable supporting part 5 . This means that when the ciliary muscle contracts the centre 6 of the lens part 2 is moved upwards with respect to the optical axis 7 . Such a movement is indicated in FIG. 2 a by a, where a can be between 0.1 and 1.5 mm.
  • the radial direction is indicated by arrow 11
  • arrow 12 in FIG. 2 b indicates the axial direction.
  • the reading part 8 By constriction of the ciliary muscle 14 , which normally takes place when starting to read anyway, the reading part 8 will be pushed in front of the user's optical axis. If the user at the same time looks downwards, as is usual, reading can be optimised.
  • FIG. 3 illustrates a variant of the invention.
  • the intraocular lens is indicated there in its entirety by 21 and consists of a lens part 22 and an additional lens part 23 .
  • the lens part 22 is arranged inside the ciliary muscle in the way described above, there being a deformable supporting part or haptic 25 and a non-deformable supporting part or haptic 24 .
  • the distance part is indicated by 29 and the near part by 28 .
  • the centre of the lens is 26 , while the optical axis of the eye concerned is indicated by 27 .
  • the additional lens part 23 is made as a prism that tapers in a downward direction.
  • non-deformable supporting part 23 Opposite the non-deformable supporting part 23 is a deformable additional supporting part 35 of the additional lens 23 .
  • a non-deformable additional supporting part of the additional lens 23 is indicated by 36 and is located at the height of the deformable supporting part 25 .
  • lens 22 When the ciliary muscle contracts, lens 22 will be displaced upwards with respect to the optical axis of the eye concerned.
  • the prism will perform an exactly opposite movement, in other words downwards as indicated by arrow 38 . Because of this the effect of the image shift from the distance part to the reading part can be compensated or provision for further corrections in the eye can be made.
